Achieving highly stable sodium metal batteries with self-adapting and high-ionic-mobility ceramic fiber membranes.

Tough issues like sodium (Na) dendrite growth and poor anode reversibility hinder the practical application of sodium metal batteries (SMBs) with moderate liquid electrolytes. To settle these problems, using a smart self-adapting AlSiO ceramic fiber (CF) membrane is demonstrated to enable homogeneous Na depositions and inhibit the dendritic growth. This inorganic membrane itself has superb thermal stability, high ionic mobility (Na transference number: 0.

Efficacy and mechanism of acupuncture for ischemic poststroke depression: Study protocol for a multicenter single-blinded randomized sham-controlled trial.

Introduction: Poststroke depression is a serious and common complication of stroke, especially the ischemic poststroke depression. Antidepressants are used in poststroke depression, and acupuncture may be an alternative approach. However, the efficacy and mechanism of acupuncture for poststroke depression has not been confirmed.
